It's just a very simple question: Why are males so immature? What is the problem?
I can't help but chuckle at your question. The fact is this: G‑d created men and women, and in truth men mature more slowly than women. That's why a boy is bar-mitzvah at 13, while a woman reaches the age of halachic maturity at 12.
A woman is created with more emotional insight, and that's why she often carries the responsibility of the relationship. In Jewish life, it's traditional that she light the candles for Shabbat, creating light and clarity in her home. (Although the mitzvah of candle-lighting is for the home—and certainly a man may fulfill this—when there's a woman in the home it's always been her role to do so.)
Much more, of course, to be said on this subject.
